Title: Compact multi-frequency antenna with multiple ground and radiating elements
Inventor: BEREZIN MAKSIM
IPC: H01Q5/378
Filed: 2006-07-03
Abstract: An antenna comprises an insulating substrate 403 with first and second conductive portions 501, 502 on opposite respective surfaces of the said substrate. The first said portion 501 provides a first quarter wavelength resonator for frequencies in the range of 800 MHz to 1000 MHz and the second said portion 502 provides a second quarter wavelength resonator for frequencies in the range of 1200 MHz to 2000 MHz. The said first and second radiators 501, 502 have no direct galvanic connection. The substrate 403 also carries a ground plane portion 509. The substrate 403 is separated and supported by insulating support columns 405 from a conducting support member 301 which provides at least part of a ground plane. The conducting support member 301 may be electrically connected via a conductive shorting pin 411 to the ground plane portion 509 and the second conducting portion 502. The central conductor 505 of a coaxial cable 409 may be soldered to the first radiator so that it can supply a feed signal to the said first radiator 501. The outer conductor 508 of the coaxial cable 409 may supply a feed signal to the second radiator 502 via the third conducting portion 509 and conductive via elements 511. Other conductive elements associated with an imager device may be used to improve the impedance matching of the antenna elements. The compact, efficient multi-frequency antenna may be suitable for use in a wireless communication device.

Inventor: AHMED ZAHIR
IPC: C08J3/20
Filed: 2007-04-27
Abstract: A label comprises a textile material, having at least a portion which comprises a laser sensitive yarn. The yarn is configured such that exposure of the yarn to laser radiation of a predetermined type modifies an optical property of the yam without burning or scorching, to provide visible contrast between a portion of the yarn exposed to the laser radiation and a portion of the yarn not exposed. The textile is preferably woven and the warp or weft yarns may be laser sensitive. The optical property, such as colour or reflectivity, is preferably only altered when the intensity of the laser exceeds that of direct sunlight. A low powered carbon dioxide laser is preferred. The yarn may comprise a fibre coated with a laser sensitive material, such as a dye, before or after weaving or a fibre having a laser sensitive material incorporated within at the melt stage. The fibre may be any mix of polypropylene, polyamide or polyester. The laser sensitive material may be EVA (ethylene vinyl acetate).

Title: Method and System for Controlling Smartcards
Inventor: COWCHER PAUL RANDLE
IPC: G06K17/00
Filed: 2007-06-26
Abstract: This invention relates to a method and system for controlling smartcards 300 which are capable of audiovisual output. Data stored 304 remotely from the smartcard is monitored for indication of a predetermined criterion, for example indication of a certain level of funds in a smartcard user's bank account. A control signal can then be communicated to the smartcard for controlling the update of audiovisual output from the smartcard. The control signal can thus be communicated to the smartcard in response to a trigger generated externally of the smartcard. Data relating to audiovisual output of the smartcard may be stored on the smartcard itself, in which case the control signal may indicate to the smartcard to update its audiovisual output according to audiovisual data already present on the smartcard.

Title: Wrap spring clutch and fan arrangement in a chainsaw
Inventor: DOUGLAS JAMES STUART
IPC: B27B17/08
Filed: 2007-07-20
Abstract: A chainsaw (11) comprises a motor (16) in drivable communication with a chain (13) via an output shaft (15) and a sprocket (12) carried by a driven shaft (14). The output shaft (15) communicates with the driven shaft (14) via a driving gear wheel (18) and a wrap spring clutch (19) coupling the rotation of the driving gear wheel and the driven shaft. The driving gear wheel comprises an axial stub shaft (18a). The clutch covers the stub shaft and the driven shaft to provide selective drive between them.
